Just imagine a scenario where you have lost the home key. You might have dropped it in some place, and do not have any idea or memory about where you lost it. You are stranded in front of your home unable to enter into it. You might be blaming yourself for being such a stupid idiot, and not taking care of the keys. This type of situation is quite common, and you don’t need to blame yourself for the mishap. It could happen to anyone at any given moment.
